WAN IPv6 Prefix Delegation doesn't work
I bought recently a new FVS328Gv2 as replacment for an older D-Link DIR-825. The FVS318Gv2 is connected to an AVM Fritz!Box 6490 which is the internet access router of my provider. The Fritz!Box 6490 allows to use a second router on its LAN side and offers an IPv6 subnet prefix via prefix delegation. This IPv6 prefix delegation has been working well with my DIR-825 so the Fritz!Box seams to be setup properly by me. Let me now explain the steps taken with my new FVS328Gv2: 1. Unboxed the device and checked that it has FW Version 4.3.1-11 2. Upgraded to the latest version from netgear portal 3. Now the FVS328Gv2 is using FW Version 4.3.4-2 4. Setup IPv4 WAN via DHCP -> works fine Fritz!Box 6490 delivers address, gateway and DNS to FVS328Gv2 Access to the internet is working and at good performance rate. Fritz!Box 6490 has a static IPv4 route into my private LAN on FVS328Gv2. 5. Setup IPv6 WAN via DHCPv6 with IPv6 Prefix Delegation -> *** does not work *** FVS328Gv2 gets an IPv6 address and gateway (the Fritz!Box 6490). But WAN link status remains on 'connecting... ' and never ends. Some time later it gets a primary DNS server (the Fritz!Box 6490). But WAN link status remains on 'connecting... ' and never ends. I never see a delegated prefix on the LAN configuration pages of the FVS328Gv2. So I can't get IPv6 internet access from the LAN side of the FVS328Gv2. The Fritz!Box does not offer static IPv6 routes so setup the FVS328Gv2 WAN manually will not work. Note: The Fritz!Box gets an IPv6 prefix of length 62 from my ISP. The former DIR-825 has been assigned properly a sub-prefix of the 63 by the Fritz!Box. What am I doing wrong? Hope for any help.
